please help tranny trouble
Hello first time poster. I have 1999 ford f250 7.3 diesel. This truck ran good the first month I had it. It has 175,000 mi on the clock. Okay heres the issue. After about a half hour of driving the trannsmission starts acting up. When you go to pull away from a dead stop it will not go. Sometimes it kicks hard other times you have to rev it and it acts like it "builds Pressure" and it gradually takes off. Also going down the interstate it will shift into second but not into third but not all the time. It will hit the rev limiter and just will not shift so ya end up limping home at 55 mph. The funny thing is every day is different from the other sometimes it behave sometimes not. Any help would be greatly appreciated
Thanks, James

You might need to check the fluid level. If that is good and doesn't smell burnt, drop the pan. If you see stuff in it, Give Brian's Truck Shop a call because that is probably where you are going. Ask me how I know

the funny thing is i bought it in texas and drove it back to missouri. About a month after the trip it started acting up. Already changed the fluid and filter. It was dirty, had the stock oem filter still in it.

Been down this same road. Keep on driving it and revving it up to get it to move and then maybe you can do a whole lot of damage. The tranny is most likely junk already. I had mine redone by a drag racing transmission builder and I flat out love it. Except for in stop and go traffic where the first to second shift nearly chirps the tires, but that is what I asked for, so that is what I got.

Those are pretty much the same symptoms mine had when it took a dump. Sounds like its time for a new tranny. Dont feel bad, I only had mine 6 months when I went through it.

firebrd is correct on any trans over100K that has never been serviced you run a risk of accellerating its demise, seen it lots of times and heres how: trans fluid is just like motor oil in the respect it has an additive package that degrades over time & high temps if you do not service it ( fluid & filter change) it will fail. Any new atf is high in solvents (syn fluid is more temp stable seemes to keep things cooler) and can wash down worn clutch packs and it will quit working. Most owners manuals say you can go 50K between service. If you work your stuff hard cut that in half, I do. I know it seemes like overkill but 70.00 to 100.00 for a service is cheap compaired to 2500.00 for a rebuild. Now comes the disclamer: stuff can & will break, parts fail ect.... but P.M. service is your best insurance Spent the last 6 years in sales for AAMCO dealer in central Iowa with 4 centers the above statement is gathered from what I have seen......Bill.

Many people ignore the trans for over 100k miles. The fluid has been worn out for many of those miles, and now the trans has problems. If they continue to ignore it, it will soon die. They decide to change the fluid because it is not working right. It isn't working right because it is damaged. They change the fluid and it dies. It would have died with the old fluid, too. They wore it out with the old fluid that wasn't capable of lubricating or holding the friction elements. New fluid and it's higher detergents (solvents?) didn't cause the failure, the failure was due to not changing over the life of the trans. Keeping the old fluid in it won't prolong it's life at all.
